I-Microsoft Mathematics iyithuluzi elihle lomfundi (1)
Inkampani yakwaBill Gates (nakuba isivele “ingumuntu ozimele”, kodwa phela “ubuso” bayo obungenakucimeka) muva nje ithumele ku-inthanethi ithuluzi elikhulu lalolu hlobo, ososayensi bekhompyutha abalibiza nge-CAS (I-Computer Algebra System? I-Computer Algebra System) ). ). Kunamathuluzi anamandla kakhulu laphaya, kodwa ingabe leli libonakala lifaneleka ngokukhethekile ezidingweni zomfundi? ngisho nomfundi wasenyuvesi yobuchwepheshe. U-MM angakwazi ukuxazulula noma iyiphi i-equation, imisebenzi yesakhiwo sokuguquguquka okukodwa noma okubili, ukuhlukanisa nokuhlanganisa, futhi unamanye amakhono amaningi, esizokhuluma ngawo kamuva.
Yenza izibalo kokubili ngezinombolo (ezinombolo zangempela neziyinkimbinkimbi) futhi ngokomfanekiso, iguqule amafomula ngokufanele. Kubalulekile ukuthi ingafiki ekukhipheni umphumela wokugcina, kodwa imele izibalo ezimaphakathi nezizathu; lokhu kusho ukuthi ilungele ukuphatha zonke izinhlobo zemisebenzi yasekhaya. Umkhawulo kuphela ukuthi kufanele wazi isiNgisi. Hhayi-ke, i-Mathematical? IsiNgisi singamagama angamakhulu ambalwa kuphela?
Lolu hlelo lubizwa ngeMicrosoft Mathematics, belubiza cishe amadola angama-20, njengoba inguqulo yesine imahhala ngokuphelele. Nakhu . Ngaphambi kokwenza lokhu, nokho, qiniseka ukuthi ikhompuyutha yakho ihlangabezana nezimfuneko; futhi zimi kanje: isistimu yokusebenza okungenani i-Windows XP nge-Service Pack 3 (yebo, ingaba i-Vista noma i-Windows 7), i-Microsoft .NET Framework 3.5 SP1 ifakiwe, iprosesa enejubane lewashi lika-500 MHz (ubuncane) noma 1 I-GHz (kuyanconywa), 256 MB ubuncane be-RAM (500 MB noma ngaphezulu kuyanconywa), ikhadi levidiyo elinenkumbulo okungenani engu-64 MB, okungenani u-65 MB wesikhala samahhala sediski.
Lezi akuzona izidingo ezinkulu kakhulu, ngakho-ke ngemva kokulanda ifayela lokufaka ekhelini elinikeziwe, siqhubekela ekufakweni kwe-banal bese siqhuba uhlelo.
Iwindi lomsebenzi elilandelayo lizovela:
Okubaluleke kakhulu kwesokudla: kukhona amawindi amabili azoba nalutho uma uvula uhlelo. Ezansi kakhulu (ezimhlophe, ezincane, ezinohlamvu? Futhi?) Kukhona iwindi lolwazi, empeleni okungadingekile, nakuba phakathi nezibalo liqukethe izincazelo namathiphu; okwesibili? iwindi lokufakwayo kwefomula, singakwenza kokubili sisuka kukhibhodi futhi sisebenzisa "isilawuli kude"? ngezinkinobho; endabeni yokukhetha ithuluzi lokugcina lokusebenza nohlelo, udinga igundane kuphela. Umphumela wokubala? usho amafomula aguquliwe noma igrafu ehambisanayo? avela efasiteleni lesibili lendawo yokusebenza, ekuqaleni empunga, enegama elithi "Ishidi Lokusebenzela"; Kuyaphawuleka ukuthi eduze kwethebhu enalo mbhalo kukhona ithebhu "Ishadi", esizoyisebenzisa. kulula kangakanani ukuqagela? uma sifuna ukufunda amagrafu asebenzayo.
Lapho ufunda ekuqaleni isixhumi esibonakalayo sohlelo, kufanele unake izinkambu ezintathu ezikhonjiswe imicibisholo esithombeni esinamathiselwe. Lena inkinobho yokukhetha indawo yokubala ("Yangempela" yezinombolo zangempela noma "Inkimbinkimbi" yezinombolo eziyinkimbinkimbi); ifasitela "Izindawo zamadesimali", okungukuthi, ukubeka ukunemba kwezibalo (inani lezindawo zamadesimali; kungcono ukushiya "Akulungisiwe" - khona-ke ikhompyutha izokhetha ukunemba ngokwayo); Ekugcineni, inkinobho ye-Equation Solver, uma icindeziwe, ikhompuyutha izohlaziya amafomula afakiwe futhi, ngokunokwenzeka, ixazulule izibalo. Izinkinobho ezisele kufanele zishiywe zingashintshiwe okwamanje (enye yazo, ebhalwe ukuthi "Ink", iwusizo kuphela kumadivayisi wesikrini esithintwayo).
Isikhathi sokwenza izibalo zokuqala.
Masixazulule i-quadratic equation
x2-4 = 0
Indlela 1 yokufaka umsebenzi: Faka ikhesa ebhokisini lokufaka lefomula bese ucindezela izinkinobho x, ^, -, 4, =, 0 ngokulandelana kwazo. Qaphela ukuthi uma usebenzisa uphawu ^ njengophawu lokuchaza, kuzosetshenziswa umcibisholo oya phezulu.
Indlela 2 yokufaka umsebenzi: kusilawuli kude? ohlangothini lwesobunxele sicindezela u-x oguquguqukayo, uphawu lokuchaza ^ kanye nezinkinobho ezihambisanayo ezengeziwe.
Kuzo zombili izimo, kunjalo, isibalo sethu sizovela efasiteleni lokufaka lefomula. Manje cindezela inkinobho ethi Enter. kwesokudla senkambu yokufaka? futhi efasiteleni lemiphumela phezulu kukhona irekhodi elimayelana nomsebenzi ngolimi lohlelo:
I-solvex2-4=0,x
okusho ukuthi "xazulula isibalo kubakaki ngenhlonipho"), futhi ngezansi kunemigqa emithathu enama-plues aluhlaza amakwe "njengezinyathelo zesixazululo". Lokhu kusho ukuthi uhlelo seluthole izindlela ezintathu zokuxazulula inkinga futhi lusishiya nokukhetha esifuna ukukudalula (singababona bonke). Uhlelo olungezansi lubala izinto ezimbili.
Isibonelo, ake sithuthukise indlela yesibili yesixazululo. Nakhu esizokubona esikrinini:
Njengoba ubona, uhlelo lukhombisa ukuthi lwengeze u-4 ezinhlangothini zombili zesibalo, lase lithatha impande eyisikwele, lathatha ngokuthi hlanganisa nokususa? futhi wabhala phansi izixazululo. Ingabe kwanele ukukopisha yonke into ku-notepad? nomsebenzi wesikole wenziwa.
Manje ake sithi sifuna igrafu yomsebenzi
awu = h2-4
Senza lokhu: shintsha ukubuka kwesikrini kube "Igrafu". Iwindi lokufaka i-equation lizovela; singafaka izibalo eziningana ngayinye ngayinye ukuze sibone ukuthi zihlobana kanjani. Ekuqaleni, kuboniswa izinkambu zokufaka ezimbili kuphela, kodwa sizofaka eyodwa kuphela endaweni enomthunzi. Singasebenzisa ikhibhodi, noma? njengangaphambili? kusuka kusilawuli kude. Bese uchofoza inkinobho ethi "Igrafu". ? futhi kuzovela igrafu, njengakusithombe-skrini esinamathiselwe.
Kuyaqapheleka ukuthi ngemuva kokukhetha iwindi lehluzo, iribhoni yemenyu izoshintsha futhi sizokwazi ukwenza ukufometha okuhlukahlukene kweshadi. Ukuze sikwazi ukusondeza noma ukuphuma, sifihle izimbazo, sifihle umngcele wangaphandle, sifihle igridi. Singakwazi futhi ukunquma ububanzi bokuhlukahluka kwamapharamitha abonisiwe futhi silondoloze igrafu engumphumela njengesithombe kumafomethi amaningana ezithombe ezidume kakhulu. Phansi impela kwewindi Lezibalo Nemisebenzi? kukhona futhi inketho ethokozisayo yokubonisa izilawuli zokugqwayiza zeshadi elithi "Izilawuli Zegrafu"; Ngikweluleka ukuthi uhlole umphumela wokusetshenziswa kwabo.
Ezinye izici zohlelo? esikhathini esizayo.
